To allwkom it may concern: v v I v Be it known that I, BUDD G. NICE, a citizen of the United States, residing at Ogontz, Montgomer, county, Pennsylvania, have invented ce Q11 Improvements in Antifriction-Wheels, of which the following is a specification.

My invention is an improved ball hearing construction especially designed for use in 10 or in connection with traction and belt wheels or pulleys, and its leading object is to provide a simple and inexpensive wheel, comprising a sheet metal body having a race in combination with a hub having a race and balls in said races, whereby said body is journaled on said hub and adapted for taking radial thrusts.

In the drawings, Figure 1 is a side elevation of a traction or belt wheel embodying my improvements; Fig. 2 is a sectional view taken through the axis of the construction shown in Fig. 1; Fig. 3 is a side elevation of a second form of belt wheel or pulley embodying my vimprovements; and Fig. 4 is a sectional-view taken through the axis of the construction shown in Fig. 3.

The form of the invention shown in Figs. 1 and 2 comprises the soft laminated metal webs 1 provided with outwardly turned peripheral flanges 2 forming substantially cyli drical bearings and the concentric interior flanges 3 forming a substantially concave bearing or channel, the webs being secured together by rivets 4. A soft metal peripheral band 5 is disposed on the flanges 2 and is provided with inturned flanges .6 engaging the flanges 2, whereby the latter are braced, the band is held in position, and a strong peripheral construction is provided. Unequal hard metal race ring sections 7 and 8 are disposed within the outwardly expanded flanges 3,-the juncture of the sections being eccentric to the central plane of the wheel so that resultant thrusts transmitted to the ring sections are not at the joint. A hard metal hub 9, having a circular race 10, is disposed within the flanges 3 with the race 10 in registration with the race 78. Balls 11 are disposed in the raceslO and 78 whereby the wheel body isrevoluble on the hub through a ball bear- Specification of Letters Patent.

body or hub relatively to each other, and the bearings are protected.

The form of the invention illustrated in F lgs. 3 and 4 comprises a wheelbody having the soft metal Webs 14 (connected by rivets 14') with outwardly extending peripheral flanges 15 thereon (forming a peripheral channel 16 for carrying a round belt) and the outwardly expanded internal flanges 17 forming a concave channel for holding the unequal hard metal race ring sections 18 and 19. A hard metal hub 20 has its axis disposed in the axis of the wheel body and is provided with a peripheral race 21 register- -ing with the race formed by the ring seccross section intersecting the planes of said webs, a band on said peripheral flanges and Patented Mar. as, 19116.

provided with inturned flanges engaging the outer edges thereof, a race ring conforming to and disposed within said interior flanges, and means comprising a hub and balls engaging said hub and ring whereby said body is supported and journaled.
